Answer:
Perimeter = 12+4pi
Area = 16+8pi
Step-by-step explanation:
Description of the assumed shape:
A rectangle 2 x 8 superimposed on a semi-circle of radius 4.
Perimeter:
P = 2+8+2+(4)(pi) = 12+4pi
Area :
A = 2*8 +(pi)4^2/2 = 16 + 8pi
Ok the formula for this is 2(lw +hw+hL)
2(30+35+42)=2(107)=214 square feet
Answer:
the required equation is; y = 21 sin(πt/6)
Step-by-step explanation:
Given the data in the question;
Water rises above sea level = 21 ft
Water drops below sea level = 21 ft
so
maximum = 21 ft and also
minimum = 21 ft
Amplitude = ( maximum + minimum ) / 2
Amplitude = ( 21 + 21 ) / 2
Amplitude = ( 21 + 21 ) / 2 = 42/2 = 21 ft
Period = 12 hours
and we know that; period = 2π/b
so
12 = 2π/b
12b = 2π
b = 2π / 12
b = π/6
Standard equation for simple harmonic is; y = asin(bt)
we substitute
y = 21 sin(πt/6)
Hence the required equation is; y = 21 sin(πt/6)
The answer is 3 because you need to use the last equation which is x is greater than or equal to 3.it doesn't make sense to use any of the other two equations because it asked what is the value of g(3).hope this helps if it does please mark brainliest
Answer:
It really determines what geometry is.
In simple terms geometry is just shapes.
That’s it really.
You have multiple theorems, postulates, and definitions to help you assist in proofs of theorems or jsut understanding of basic shapes.
